### Stabilizability and percolation in the infinite volume sandpile model

Anne Fey, Ronald Meester, and Frank Redig

#### Abstract

We study the sandpile model in infinite volume on ℤ^{d}. In particular, we are interested in the question whether or not initial configurations, chosen according to a stationary measure *μ*, are *μ*-almost surely stabilizable. We prove that stabilizability does not depend on the particular procedure of stabilization we adopt. In *d*=1 and *μ* a product measure with density *ρ*=1 (the known critical value for stabilizability in *d*=1) with a positive density of empty sites, we prove that *μ* is not stabilizable.

Furthermore, we study, for values of *ρ* such that *μ* is stabilizable, percolation of toppled sites. We find that for *ρ*>0 small enough, there is a subcritical regime where the distribution of a cluster of toppled sites has an exponential tail, as is the case in the subcritical regime for ordinary percolation.
